Wales have delayed naming their side to face England at Twickenham on Saturday until the full-back Lee Byrne's appeal against his two-week suspension for re-entering the field of play without permission during the Ospreys' Heineken Cup victory over Leicester last month.

The Wales coach, Warren Gatland, had intended to reveal his starting line-up tonight but postponed the announcement until Byrne's appeal is heard. European Rugby Cup has set no date for the hearing but Tuesday is regarded as the most likely date.

Byrne is the only specialist full-back in the Wales squad and Gatland had made no secret of the fact he was going to pick the 29-year-old, who missed Wales' autumn internationals with an ankle injury. James Hook played out of position there in November but Wales want their most creative player to be closer to the action in midfield.

Byrne, who came back on to the field against Leicester for 50 seconds after being treated for a cut toe, became the first player to be banned for re-entering the field without permission when a three-man ERC disciplinary panel ruled him him out for two weeks on Friday."It seems a tough call," said the Wales and Ospreys wing Shane Williams. "The game with Leicester was so quick that even I didn't realise what was happening. People look for blame and unfortunately Lee has taken the brunt of it. He has been in top form in recent weeks and it is a harsh way to be left out of a game. I hope we get him back."

The suspension has reopened the debate over whether a sanction for an offence in one tournament should impact on another. One option for the appeal panel would be to adjourn the case, lifting Byrne's suspension in the process, until 5 April when any ban would rule him out of the Heineken Cup quarter-final against Biarritz in San Sebastian the following Saturday.

England, meanwhile, will be without the flanker Magnus Lund for up to eight weeks after he ruptured ligaments in a finger playing for Biarritz last week.
